Is there some version or other identification somewhere ? If not there
should be. ie, we're going to add things here. For example, what about
the vector registers ? Also, some CPUs will have more HW debug registers
than just the DABR (we plan to add support for all the BookE architected
IACs and DACs for example), etc...
